Copper Flotation - Mineral Processing & Metallurgy

19/03/2017· The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation…

Froth flotation - Wikipedia

04/03/2005· Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of …

How to Operate a Flotation Circuit

19/03/2017· A flotation machine needs deep froth in order to allow time for unwanted mineral to drain from the froth bubbles back into the pulp. Also, a high pulp level isn’t so important in a cleaner cell, because recovery isn’t what you’re after so much as grade of concentrate. Therefore, in a cleaner cell, a froth depth of at least 8 in. is required in most cases, and you have more leeway in ...

60 Centuries of Copper: The Flotation Process

The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface. In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the ...

Induced-air flotation cell | FLSmidth

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the induced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise to the top as froth for concentration and collection.
